Abstract: A data transmission from a control device (100) to a load (52) is carried out via a load line (40). The control device (100) comprises a first switching means (121) and a second switching means (122) which are switched in a series circuit between an input terminal (101) and an output terminal (102) of the control device (100). A control circuit (110) is coupled to the first switching means (121) and the second switching means (122) and is configured to generate a control signal (ctrl) for controlling the first switching means (121) and/or the second switching means (122) so as to transmit data bits.

Abstract: A data transmission from a control device (100) to a load (50) is carried out via a load line (40). In the method, a switching means (106) is controlled in order to increase a resistance of a line path between an input terminal (101) and an output terminal (102) of the control device (100). A voltage is detected in the control device (100) in order to identify a phase position of a supply voltage. The supply voltage is influenced depending on the identified phase position and the data to be transmitted in order to transmit a data packet.

Abstract: A circuit for the generation of ignition pulses for a lamp has: an ignition pulse transformer, a device for the generation of ignition pulses (ignition pulse generator) at a primary winding of the ignition pulse transformer, which are transformed in the secondary winding of the ignition pulse transformer, a voltage detector for the detection of the voltage value of the transformed ignition pulses, and a voltage regulator for regulating the voltage value of the transformed ignition pulses to a predetermined reference value. The ignition pulse generator has, in a series circuit, a pulse capacitor and a switch, parallel to the secondary winding of the ignition pulse transformer and the lamp, wherein the regulator for the voltage value of the transformed ignition pulses sets at the pulse capacitor the voltage applied at an ignition time point. The voltage at the pulse capacitor can be set by means of selection of the switch-on and/or switch-off time points of the switch.
